Abstract
The utility model discloses a kind of pressure release type petroleum pipeline deferent box cupling structure, including steel conduit, pipe box cupling, outer cover, it is characterized in that, steel conduit two ends respectively add a pipe box cupling, steel conduit inwall is provided with internal lining pipe, provided with closure vacuum layer between pipe box cupling and steel conduit, it is socketed with the outside of pipe box cupling on outer cover, pipe box cupling and is connected with lever relief valve.
Description
Technical field
The utility model belongs to petroleum pipeline technical field, more particularly to a kind of pressure release type petroleum pipeline deferent box cupling knot
Structure.
Background technology
Current oil liner oil pipe is generally operational in hundreds of meters of underground, using in oil pipe in built-in anticorrosion antiwear
Lining, can prevent the abrasion and the internal corrosion of oil pipe of sucker rod and tube inner wall.Due to well depth, the thick heat transfer of the underground in addition temperature of oil
Poor big, and steel pipe thermal resistance very little, result in by oil pipe to delivered downhole heating evaporation is that thermal loss is big, while steel conduit
Larger pressure is also subjected to, with continuing to develop for heat-insulating technique, but the heat-insulating problem of vacuum oil tubing coupling never has
To good solution, the proportion that the heat loss of tubing coupling accounts for heat loss in oil pipe pipeline is increasing, and heat insulation pressure-resistant effect is not
It is too preferable.
Utility model content
The utility model is intended to overcome the defect of prior art there is provided a kind of pressure release type petroleum pipeline deferent box cupling structure, has
Have simple in construction, production cost is low, the characteristics of service life is long.
In order to solve the above-mentioned technical problem, the utility model provides following technical scheme：
A kind of release petroleum pipeline deferent box cupling structure, including steel conduit 1, pipe box cupling 2, outer cover 3, it is characterised in that steel pipe
The two ends of road 1 respectively add a pipe box cupling 2, and the inwall of steel conduit 1 is provided with internal lining pipe 11, provided with closure between pipe box cupling and steel conduit
It is socketed with the outside of vacuum layer, pipe box cupling on outer cover 3, pipe box cupling and is connected with lever relief valve 4.
Further, lever relief valve is made up of needle valve, pressure gauge, main valve, pilot valve and connecting tube.
Further, the outer cover is tubular-shaped structures, and outer cover is made up of vinyon composite.
Further, the outer cover is spliced by four mutually isostructural segmental arcs 31, and segmental arc side wall is radially respectively set at two ends
It is equipped between an edge protector, two adjacent shield sections and is fixedly connected by bolt 32.
Compared with prior art, the utility model has following beneficial effect：
The utility model is simple in construction, and production cost is low, and service life is long；By being socketed overcoat, pipe in pipe box cupling appearance
The heat-insulating property that closure vacuum layer strengthens petroleum pipeline is installed, pipe box cupling is in use, pipe box cupling connects between box cupling and steel conduit
Release can be carried out to the pressure in pipeline by being connected to lever relief valve.
